Galadriel and her redemption

[Carannillion]

Actually, this is sort of a side thread to the post 'Eowyn Arwen Galadriel', but it would be too much off topic to start it there, so here we go..

In the aforementioned topic, it is mentioned that one of Galadriel's plusses is that she was strong enough to stay in Middle-Earth until 'the end', not forsaking it. In this post I think [img]smilies/confused.gif[/img] it will be made clear that she had no choice but to stay in Middle-Earth.

According to the Doom of the Noldor, all of those who left The Undying Lands after the Kinslaying would fall under this curse.

This includes Galadriel.

The Curse says that
"Tears unnumbered shall ye shed; and the Valar will fence Valinor against you, and shut you out, so that not even the echo of your lamentation shall pass over the mountains.

Those who are of the House of Fëanor, and all who follow them, shall die by weapon and by torment and by grief, and stay in the Halls of Mandos along with the spirits of those they killed in the Kinslaying. Those who do not die
"shall grow weary of the world as with a great burden, and shall wane, and become as shadows of regret before the younger race that cometh after. The Valar have spoken."

Galadriel did not die (duh...) but still, when the company comes to Lothlórien, she seems as beautiful and radiant and majestic as none other in Middle-Earth.

Question 1.
What was she like when she dwelt in Valinor? And how incredibly fantastic must then the Valar be, as they are beyond comparison with any of the Children of Ilúvatar..?

Question 2.
After the War of the Ring, Galadriel went over the sea, back to the Undying Lands. The Curse of Mandos does not say anything about an opportunity for forgiveness - the moment they stepped out of the Undying Lands, the way back was closed forever, save in death or at the end of time, when all shall return to Ilúvatar. How was Galadriel then allowed to return? Her effort against Sauron?

BTW: Don't get me wrong, I don't 'hate' Galadriel, she is my favourite as well, but I just wanted to get some input on this subject. It's been nagging me for a while now.
